The EJX630A is a high performance, in-line mount gauge pressure transmitter and is part of the EJX-A series. It features a single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam pressure. The EJX630A outputs a 4 to 20 mA DC signal corresponding to the measured pressure. They also feature quick response, remote setup and monitoring via BRAIN or HART communications, diagnostics, and optional status output for pressure high/low alarm.
EJX-A series models in their standard configuration, with the exception of the Fieldbus and PROFIBUS types, are certified as complying with SIL 2 safety requirements.
- Accuracy: ± 0.04% Accuracy (Optional ± 0.025%)
- Response Time: 90 msec
- Stability: ±0.1% of URL per 15 years
Enhanced Product Quality: The EJX630A with DPharp digital sensor offers the performance needed to run your operations at peak performance. This ensures on-spec product, reduced waste, and improved yield, helping you increase profitability.
Other pressure sensor technologies require an analog to digital conversion before the signal can be processed, introducing additional errors. In Yokogawa’s pressure transmitters, the DPharp sensor directly outputs a digital signal, eliminating the need for analog to digital conversion and improving performance.
Tighter Process Control
Poor performing pressure transmitters can lead to you having to run at a lower than desired set point in your control loop or scrap product that doesn’t meet spec. The DPharp sensor exhibits greater linearity and repeatability with no inherent hysteresis, providing tighter process control.
Reduced TCO: The EJX630A reduces total cost of ownership by having safety as standard, extending calibration intervals, and utilizing a common communication platform for all protocols.
Extended Caliboration Check Intervals
Yokogawa EJX-A series pressure transmitters have the long-term stability of ±0.1% per 15 years under all operational conditions, reducing calibration frequencies. As you gain experience with these transmitters, the interval between calibration checks is extended. Long-term this can help reduce your maintenance cost by up to 34%. Spend your time where it is needed.
Increased Plant Availability: The proven DPharp technology of the EJX630A increases plant availability with its advanced diagnostics and quicker resolution of maintenance issues through multiple communication options. Verified by independent third parties around the world, our transmitter provides superior reliability and performance.
